Hello World ！

Hello, my name is Mei Chen. I’m a Java backend developer with two years of full‑time experience, and I graduated from Xihua University with a degree in Computer Science.

Currently, I work at Chengdu XX Technology, where I’ve been developing backend services for hospital management systems. My main tech stack includes Spring Boot, Spring Cloud, MySQL, Redis, and Docker. I’ve also used SoToken for authentication and permission control, and I’m familiar with RESTful API design and Git for version control.

One of my key projects is a Hospital Performance Evaluation System. I handled permission storage with Redis, integrated SoToken for security, and deployed the whole system (Vue, Java, MySQL, Ubuntu) on a hospital intranet using Linux commands and MobaXterm.

I also have experience with microservices – for example, in a document management project, I worked with gRPC and Docker (though that part used Go, the architecture pattern is something I understand well). On the Java side, I’ve done secondary development based on RuoYi (SpringCloud + Security) for a project management system.

Beyond coding, I write technical blogs (over 100 posts on CSDN), and I actively use AI tools like OpenAI and DeepSeek to boost development efficiency. I’m a fast learner, enjoy solving backend performance problems, and work well in agile teams.

I’m excited about this backend opportunity at your company because I want to grow in a global environment and contribute my Java skills to scalable, high‑quality systems.

Thank you for listening – I’m happy to answer any questions.

“You mentioned Go in one project – why do you want a Java backend role?”
→ I’m primarily a Java developer. That Go project was a short‑term task, but my strongest and most consistent experience is with Spring Boot and Java. I’m committed to growing as a Java backend engineer.

“How do you handle permission control in a microservice environment?”
→ In my current role, I used SoToken with Redis to store user permissions and validate tokens centrally. For Spring Cloud, I’ve worked with Spring Security + JWT.

“What’s your experience with testing?”
→ I write unit tests with JUnit and Mockito. In one project, I increased test coverage to about 85% and also did integration testing for REST APIs.

“Tell me about your AI‑assisted development experience.”
→ I use AI tools to generate boilerplate code, write unit tests, and refactor legacy code. It helps me deliver faster, but I always review and understand every line before committing.
